sides are deeply notched, the angles being nearer the eyes than the 

 tips of the horns, which bend slightly inwards ; an impressed longi- 

 tudinal line, deepest and broadest behind, extends from the middle 

 of the anterior margin to a slight protuberance behind, on the sides 

 of which the stemmata ai'e placed. 



The head is flat, and somewhat hairy beneath ; the antennae arise 

 from a depressed part of the under side, nearly midway between the 

 eyes and the origin of the beak; they are 5-jointed, the joints subcy- 

 lindrical, the 1st and 3rd nearly equal, the 2nd very small, the 4th 

 smaller than the 5th, which is elongated and nearly as long as the 1st, 

 the last three are most slender at the base, and are sparingly covered with 

 short hairs. The beak reaches to the beginning of the 2nd pair of legs, 

 2nd joint the longest, 3rd thicker than the 2nd, except perhaps at the 

 end, and furnished with a few hairs. The thorax is rather wider than 

 the abdomen, and is dilated at the sides, emarginate in front, gradually 

 ascending to the middle behind, which is truncated, the extremities of 

 the truncated margin sloping forward to the rounded sides. Legs ra- 

 ther compressed, the tibiae fitting into the grooved margin of the fe- 

 mora, and the tibiae are also grooved for the reception of the 2-jointed 

 tarsus, as the insect seems, like the Histeres, and many other insects, 

 when surprized to draw in the legs, which in this way being in little 

 compass, fit into the depressed parts of the abdomen, the whole in- 

 sect then appearing just like a dirty sand-coloured pebble : the tibias 

 at the end are densely clothed with hairs, as is the sole of the 1st joint 

 of the tarsus, the hairs on the sides of the 2nd joint are longer, but less 

 thickly placed. The scutellum is narrowest at the base, and the sur- 

 face is gradually sloped down, in a rounded manner, to the edge from 

 the posterior margin in the middle, where it is highest. The external 

 margins of the hemelytra are prominent, and as they are similarly co- 

 loured to the scutellum, make the latter look broader than the thorax ; 

 the wings and hemelytra, in the only specimen I have seen, are muti- 

 lated. The figures are larger than the natural size : the upper is a 

 lateral, the lower a dorsal view. Adam White.

 Dear Sir, 



As local lists of insects generally possess interest, I have 

 thought that perhaps it may not be unacce])table to your readers to
